this is pretty sure a GCC bug - by hacking my profile.sh to use the system binaries instead the "make prof-gen" intermediate binary all is running just fine as before and like outside rpmbuild

looks like these one in combination are broken on F26 with GCC7, at least i was not able to nail it down to a single one of them when using -fprofile-generate

the resulting intermediate php 7.1.9 binary sows strange errors like open_basedir violations while mention the illegal path as a subfolder of the defined list up to non existing inlcudes which are there with correct permissions

still an iusse with gcc-7.3.1-5.fc27.x86_64

* Sun Mar 18 2018 Reindl Harald <h.reindl>
- add '-fipa-pta -fira-loop-pressure' back to compiler-flags
- '-fipa-pta': perform interprocedural pointer analysis and interprocedural modification and reference analysis
- '-fira-loop-pressure': use IRA to evaluate register pressure in loops for decisions to move loop invariants
  This option usually results in generation of faster and smaller code on machines with large register files
- we assume https://bugzilla.redhat.com/show_bug.cgi?id=1494290#c2 is fixed with GCC 7.3.1

Don't forget to run 'make test'.

This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

still a problem on F28 with GCC8 and probably even worser because more subtle, way later and only with luck found by my testsuite

throw "-fipa-pta" in the mix and php has subtle errors

Please provide a stand-alone testcase.

how should i provide a stand-alone testcase?

the php sources are public available as well as the "run-tests.php" in the tarballs, given that random own tests are failing and the whole pgo build is stopped the testsuite from php with around 150000 tests will show the fallout too
